F03D WIND MOTORS
Introduced: September 1968
Description
Wind motors encompass machines and systems that convert wind energy into mechanical power or thrust. This subclass covers wind turbines of various types, including horizontal-axis and vertical-axis designs, as well as their functional components such as rotors, blades, nacelles, and power transmission systems. Applications range from electricity generation and mechanical work production to propulsive devices. Related auxiliary systems for control, regulation, and energy conversion are also included within this classification.
